Abstract
L'invention concerne un support lisible de manière optique et son emballage. Ledit support comporte un matériau qui, avec le temps, subit au moins une modification chimique ou physique rendant ledit support illisible. Le support est scellé dans un emballage contenant une source de composé chimique qui inhibe ladite modification. En outre, ledit support est scellé dans l'emballage avec un getter du composé chimique qui, avec le temps, absorbe ledit composé chimique, ou dont la substance transforme avec le temps un composé réactif en composé non réactif. Dans un autre mode de réalisation, le support est scellé dans l'emballage avec un getter d'un composé chimique qui favorise la modification. En l'occurrence, le getter absorbe le composé chimique jusqu'à ce qu'il en soit saturé, après quoi, la teneur du composé chimique augmente jusqu'à ce que le support devienne illisible. Par exemple, le composé chimique peut être NMP, DMF, acétone ou HCl. Dans un autre mode de réalisation, le support peut également renfermer une barrière de diffusion qui inhibe le composé chimique sans l'empêcher d'atteindre une couche du support qui, avec le temps, subit au moins une modification chimique ou physique qui le rendent illisible, tandis que dans un autre mode de réalisation, la source du composé chimique renferme une barrière de diffusion. Dans un autre mode de réalisation encore, le support comporte une première couche qui, avec le temps, subit au moins un modification chimique ou physique, une seconde couche qui contient la source d'un composé chimique qui favorise cette modification, la barrière de diffusion s'interposant entre les première et seconde couches.
